Robert Plant, Alison Krauss add tour dates

Tour picks up in late September in Kansas City

NEW YORK -- Robert Plant and Alison Krauss have extended their smash hit "Raising Sand" tour through early October. The next round of dates begins Sept. 23 in Kansas City, Mo., and will wrap Oct. 5 in Saratoga, Calif.

The duo's "Raising Sand" album, released last October via Rounder, has sold 1.03 million copies in the U.S., according to Nielsen SoundScan.

"I'm surprised at the varying of the performances show to show," Krauss said last month. "Because of the personalities within the band, it has changed the show night to night, not only the show overall but each tune takes on a different character. Everything has its own identity from night to that. That's very exciting for all of us."

Sept. 23: Kansas City, Mo. (Starlight Theatre)
Sept. 24: St. Louis (Fox Theatre)
